1. (5pts) Use the following sequence for the next three questions: seq = ([1,2,3], 4, ("1", "2", "3", ("John", "Alan"]], "cat") What is the value of each expression? seq[1] seq[-2)(3)(1)(-1) len(seq) seq[2][2] What is the type of each expression? seq[2] seq[@](1:) How do you access the following list elements using bracket notation? "John" What is the result of the expression? "3" in seg seq[@][0] + seq[1] 2. (3pts) Complete the function that returns the ratio between the sum of the negative elements and the product of the negative elements of a list. def ratio_sum_product (num_list): = (1, -2, 3, -4, 0] would return -0.75 #(-2+ -) / (-2. -4) 3. (2 pts) Write the output of the following program Output: 1st = [1,2,3,4] for i in range(len(1st)): for j in Ist[i:]: print(j, enda',') print()
